22 Claims. (01. 1431-93) This invention relatesto record controlled accounting machines and more particularly to translating mechanism in combination with a combined numerical and alphabetical printer which selects certain printing characters for operation by the multiple index system and others by the single index point system.

An object of the invention is to provide a translating mechanism for an alphabetical printer 1o requiring cyclic operations for all possible printing operations, that analyzes cards during a continuous uninterrupted feeding operation.

Accounting machines of this nature are generally controlled by record cards divided into columns in which perforations or index points may be placed to indicate different characters. The controlling cards are of two general types, in one of which only one perforation is placed in a card column and in the other of which a combination of index point perforations may be placed in each column. Obviously the number of different characters which can be represented on cards of the first type is limited to the actual number of index point positions in a card column while on the second type of cards the number of possible characters is far in excess of the actual number of index point positions. The machines operating from the single hole cards are somewhat simpler in construction than those operating from the combination ,hole cards and are particularly adapted to electrical operation. It is often desirable to combine the advantages resulting from the saving in card space due to combinational hole systems with the advantages resulting from the simpler operation and construction or electrical operation of the machines operating in accordance with the system of single hole cards.

The single hole card machines are generally provided with analyzing brushes, one for each card column, beneath which the cards are passed with a continuous motion. Manifesting devices, which may be either accumulating or printing mechanisms, are driven by means operated synchronously with the feed of each card beneath the brushes and when a brush encounters a perforation a circuit is closed momentarily, the resulting current pulse either connecting the manifesting devices to or disconnecting them from their driving means. The movement of the maulfesting means during the card feeding cycle is then either directly or inversely proportional to the differential location of the index point on the card and may, therefore, indicate or register the character represented by the index point.

As is well known the Hollerith card is provided with a plurality of vertical rows or columns of index points usually numbered 0 to 9, but having two extra positions known as the 11th and 12th positions. The first ten are digit values; and a hole punched at one of these points will, when the card is run through the proper machine, cause a reproduction of .that digit value in some form usually by printing the digit or by exhibiting the same in counter wheels along with other received digit values.

The present invention uses the standard Hollerith card provided with columns of ten or twelve index points to represent not only the digits, but also the entire alphabet and other arbitrary characters. According to the present system, instead of perforating one hole for selection of certain characters, two holes are punched in a column, which taken together form a combinational hole designation. The first hole, according to its position, serves to designate which of several groups of characters containsthe character to be selected, and the second hole designates which of the several characters in the designated group is to be selected. When a single index point is used to select certain other characters that index point is used both to select a group of characters as well as one in that particular group. Mechanism is then brought into operation to print such characters.

The invention is particularly concerned with avoiding complicated circuits with their selective switches or mechanical cam and latch systems, one or the other of which have previously been essential to the proper functioning of translating mechanism of this type.

Preferably this is accomplished by the use of a pair of contact controlling sliders, one pair for each card column and arranged to be positioned by a single magnet. The sliders move synchronously with the passage of the 11 and 12 holes past the upper analyzing brushes and according to their setting prepare circuits which when the card passes the lower brushes will control the normal circuits through the holes in index positions 9 to 0 so that the type bars may present the corresponding characters to the printing line.

The alphabetical type bars are arranged to move synchronously with the passage of the cards past the lower brushes and are provided with stopsv thereon so arranged that during the passage of a single index point past the lower brushes, three stops will traverse the type bar stopping pawl in succession. The lower brushes are of greater width in a columnar direction than those usually provided in machines of this type, being so constructed that contact will be made through a hole in any index position during the interval that the three characters corresponding to such perforation are successively presented to the printing position.

A single distributor device is provided whose function is to complete three distinct circuits through the perforations in the card for each index position, the timing of these circuits corresponding to the presentation of the three characters allotted to the particular index points.

The principal object of the invention therefore is to provide novel translating mechanism for accounting machines to the end that the construction and operation of parts and the cooperation between parts may be simplified.

Another object is to provide circuit controlling devices for accounting machines so that a perforation in a single index position may control the printing of a plurality of characters depending upon the location of the control hole accompanying such perforation.

Further and other objects of the present invention will be hereinafter set forth in the accompanying specification and claims and shown in the drawings which by way of illustration show what I now consider to be a preferred em bodiment of the invention.

Card feeding mechanism Power for driving the various mechanisms is derived from a driving shaft 20 carrying a gear 21 meshing with a ring gear 22 (Fig.1). The record cards are fed singly from a supply hopper 23 by the usual card picker mechanism which in the present embodiment comprises a slidably mounted reciprocable plate 24 (Fig. 2) carrying a picker knife 25 for cooperation with the record cards. The plate 24 has a pin and slot connection 26 to an arm 27 secured to a shaft 28 which carries at its end an arm 29 connected by a link 30 (Fig. l) to a gear 31, it being observed that the link is eccentrically mounted on the gear 31 and that the latter is in mesh with ring gear 22. Each reciprocation of the arm 27 will cause a card to be fed from the hopper to the analyzing mechanisms.

The record cards are diverted from their initial rectilinear movement by a track which is substantially concentric with respect to the center of gear 22 and the cards in passing are presented to two sets of analyzing brushes 32 and 33 which sense the perforations of the record cards. The feeding of the record cards is effected by concentrically arranged pairs of feeding rollers 34 which frictionally grip the cards'and cause them to be fed in a direction determined by the shape of the track plates. The extremities of the shafts of rollers 34 are provided with gears 35 which have driving engagement with ring gear 22 and drive their motion therefrom.

The cards pass from the last pair of rollers 34 to any suitable stacker mechanism such as that designated by reference character 38 and which is of the rotary type, the drum shaft 37 having attached thereto a gear 38 meshing with a gear 39 secured to gear 31. The cards are thus fed to a stack 40 one behind the other in precisely the same order they were in originally.

As the cards pass through the feeding section current is supplied to the upper brushes 32 during the period that the 11 and 12 index point positions of the card are in cooperation with the brushes. These two index point positions are adapted to control the setting of the translating mechanism to be described later. As the cards continue through the feeding mechanism they cooperate with the lower brushes 33 to which current is'supplied during the interval that all the index point positions are in cooperation with the brushes. The lower brushes 33 are constructed of greater width in a columnar direction of the card to obtain longer duration of contact through the perforations for a purpose to be explained later.

Referring now to the card (Fig. 8) a conventional Hollerith card is illustrated and the usual digit perforations are indicated in the conventional manner. These single hole perforations are located at the various index positions in accordance with their value. The alphabetical characters B to L inclusive are represented by two perforations, one in the 11 index point position and the other in one of the index positions 0 to 9. The alphabetical characters N to Y inclusive have a perforation in the 12 index position and one in positions 0 to 9. The letter A has a single perforation in the 11 position and the letter M in the 12 position. The upper brushes 32 are adapted to sense the 11 and 12 positions and set up the circuit controlling devices in the translating mechanism. The lower brushes 33 in sensing the card beginning with the 9 positionwill sense the perforations and in cooperation with a distributing mechanism in the translating device select the proper character for printing. If the upper brushes find a perforation in the 11 position, the translating mechanism will be positioned to select one of the characters included in the zone having such supplemental-y perforation. If the upper brushes sense a perforation in the 12 position, one of the remaining alphabetical characters is to be printed, while if the upper brushes find no perforations in either of these index positions, the character to be printed will be a digit.

Translating mechanism Referring now to Fig. 1, the-cam shaft 45 of the translating mechanism is adapted to be driven in the direction indicated by the arrow by ring gear 22 through the gearing generally designated 46. The gear ratio is such that shaft 45 makes one-half revolution for each revolution of shaft 20 which as has been explained is a cyclic shaft turning once for each card fed through the feeding device.

Driven from shaft 45 through gears 47 is a shaft 48 carrying at itsopposite end a distributing commutator 49 having brushes 50 cooperating therewith. The commutator is provided with a common conducting ring 51 and a-concentrically arranged series of conducting inserts 52 electrically connected to the ring 51. A second set of inserts 53 arranged in a similar manner are also connected to the ring 51 as is also a third ring of segments designated 54. Distributor 49 makes one revolution per card cycle and the device is so timed that as the card is passing below the lower brushes 33 the inserts 52 are successively contacting the brushes 50 in time with the cooperating of the index point positions with the lower brushes and during the passage of any one index position by the brushes 33 the three adjacent inserts 52, 53, 54 corresponding to such index position will successively cooperate with their brushes 50.

The lower brushes 33 are constructed of suflicient width so they maintain contact through a perforation in the card during the cooperation of the three successive inserts 52, 53, 54 with their corresponding brushes 52a, 53a, 54a.

In a manner to be explained in connection with the circuit diagram the flow of current through the lower brushes will be controlled in accordance with the reading obtained by the upper brushes to pass through one of the brushes 52a, 53a or 54a.

In Figs. 2 and 3 a magnet 55 is provided for each card column. Each magnet has an armature 56 pivoted at 5'7 and provided with a spring 58 which is adapted to hold the armature away from the magnet. A vertical link 59 urged upwardly by spring 60 at its upper end is connected to a pivoted stopping pawl 61 at its lower extremity and is normally adapted to be latched in its lower position by armature 56 as shown in Fig. 2.

A slider 62 is mounted for horizontal movement and is provided with notches 63 adapted to cooperate with the nose of pawl 61. The operation of the parts is such that as the sliders 62 move toward theleft, as viewed in Fig. 3, under the influence of their springs 64, the notches 63 approach the nose of pawl 61 as the 11 and 12 index point positions of the card pass under the brushes 32. A perforation in the 11 position will cause energization of magnet 55 and the pawl 61 will be permitted to drop into engagement with the first notch 63 thus interrupting the further movement of the slider 62. A perforation in the 12 position will cause the pawl 61 to engage the second notch. The absence of a perforation in either of these two index point positions will permit the slider 62 to assume a third position.

Two sliders 62 are provided for each card column and they are adapted to move to the left in alternate cycles so as to permit the continuous feeding of cards. Both of the sliders are posi tioned by the same pawl 61 and while one slider is being positioned, the other is restoring and vice versa. One set of sliders is provided with depending projections 65 and the other has projections 66 cooperating with restoring bars 67 and 68 respectively.

Bar 68 is secured at its extremities in the horizontal link 69 pivoted at one end to an arm '70 loose on shaft '71 and pivoted at its other end to an arm '12 secured on shaft 73. Shaft 73, as viewed in Figs. 1 and 5, carries at its outer end a cam follower arm '74 cooperating with a cam on the shaft 45. In a similar manner the restoring bar 67 is connected to shaft '71 which in turn has a follower arm 76 secured thereto, cooperating with the cam '77 on shaft 45. Springs 78 are provided in Fig. 3 to move the bars 67, 68 to the left to permit the sliders 62 to operate.

A restoring bail 70 is secured to shaft 80 (Figs. 3 and 5) which in Fig. 1 carries a spring pressed follower arm 81 in cooperation with a cam 82. The timing of the operation of the bail 79 is such that the pawls 61 are restored to their latched position shortly after they have been tripped and since shaft 45 upon which the cam 82 is mounted rotates but once for each two card cycles, the cam 82 is provided with two oppositely located camming surfaces which operate the shaft 80 twice during the revolution of the shaft.

Each slider 62 has pivoted thereto, as shown in Fig. 3, an interposer 83 having a depending projection 84 adapted to cooperate with plungers 85 disposed in the path of movement of the projections 84. A single set of three plungers 85 is provided for each interposer 83.

Each interposer has pin and slot connection with a bell crank 86 loosely pivoted at 87. The bell crank 86 cooperating with one of each pair of interposes 83 has its free end engaged by a bail 88 while the remaining bell cranks have their free ends engaged by a ball 89. Rocking of either bail in a clockwise direction, as viewed in Fig. 3, will through the associated bell cranks, move the interposers 83 in a downward direction and depress one of the plungers 85 as shown. In the position shown in Fig. 3 the magnet 55 has been energized by the upper brushes under control of an 11 hole thus intercepting the slider 62 at the first notch 63. This in turn has located the projection 84 above the longest plunger 85. Immediately following such positioning of interposer 83 the bail 88 has been rocked in a clockwise direction lowering interposer 83 and depressing plungers 85 to close contact 90. As seen in Fig. 5a both sets of plungers 85 associated with an single card column or pair of sliders 62 are adapted to close a single set of contacts. Thus, depression of either of a pair of plungers 85 in the 11 position will close contact 90.

Bail 88 will remain in its clockwise position holding the contact 90 closed during the passage of the card by the lower brushes and since pawl 61 has been restored immediately following the lowering of interposer 83 the other slider 62 of the pair corresponding to the card column in question may now move to the left to position in accordance with the perforations in the next succeeding card and will be in position with its interposer in readiness to be depressed immediately after the previous card has been completely read by the the lower brushes 33. At such time bail 88 will be rocked in a counterclockwise direction raising the interposers 83 which have been depressed so that they may restore with their connected sliders.

At the same time bail 89 is rocked in a clockwise direction lowering the newly positioned interposers 83 and impressing a new setting upon its set of plungers 85. If the interposer were positioned under control of a 12 perforation, projection 84 would have advanced to the center plunger causing it to be depressed to close contact 91. Where no perforation is encountered by'the upper brush 32, the interposer 84 will advance to its extreme position where projection 84 lies over the shortest plunger 85 causing it to close contact 92.

In this manner a single set of contacts 90, 91, 92 are utilized to be positioned for each successive card and to control the readings of this card obtained by the lower brushes 33. In their downward movement the interposers 83 engage a resilient cross bar 93 which seats into suitable notches in the lower edges of the interposers. The sides of the notches are so inclined that as the interposers move downwardly into engagement with the bar 93 the interposers and their connected sliders 62 will be forced slightly to the right, asviewed in Fig. 3. This will cause the notches 63 which are in engagement with the pawl 61 to move slightly away from the noses of the pawls 61.

This is 'to permit the free operation of the pawls 61 during the next succeeding cycle without interference by the notches of the sliders 62 which will not have been restored at the time the alternate slider is being positioned.

The ball 88 has a pair of links 94 connected at its extremities which connect to arms 95 secured on a shaft 96 (see Fig. 5). An arm 97 secured upon the extremity of shaft 96 is connected by alink98toanarmofamember99whichhasa follower roller in engagement with a cam 100 secured upon the shaft 45. The ball 89 has a pair of links 101 at its extremities connected to arms 102 secured upon shaft 103 which shaft carries an arm 104 having connection through a link 105 to a follower member 106 which has a roller in cooperation with the cam 100. The contour of cam 100 is such that the bails 88, 89 reverse their positions each half revolution of the shaft 45 as may be seen in Fig. 3. Pivoted to bail 79 at 107 is an upwardly extending link 108 (see also Fig. 1) suitably guided and provided with pins 109 cooperating with spring pressed arms 110 secured upon rods 111. In Fig. 3 the rods 111 carry restoring plates 112 adapted to engage the upper arms of armatures 56 to restore the same when the bail 79 is operated.

Printing mechanism Referring to Fig. 6 the cyclic shaft 20 carries a pair of complementary cams 115 which cooperate with the rollers of the cam follower bell crank 116 secured upon a rod 117 to which is also attached an arm 118 having link connection to an arm 119 secured to a pivot rod 120. A pair of arms 121 is secured at opposite ends of rod and carries a bar 122 and depending links 123. The links 123 are connected at their lower ends to a bail 124 pivoted at 125. A plurality of type bars 126 are mounted for vertical reciprocation and are connected at their lower ends by links 127 to individual levers 128 pivoted at 125. The upper edges of levers 128 are urged by springs 129 against bail 124.

The operation is such that as the bail 124 is rocked in a clockwise direction spring 129 will draw upwardly on lever 128 to elevate the type bar and during the return movement of bail 124 the levers 128 will be moved downwardly to restore the type bars. Each type bar is provided with a series of notches 130 adapted to cooperate with a stopping pawl 131 held in normal position out of engagement with the notches by a latch 132. Energization of magnet 133 will rock the latch 132 to release the pawl 131 so it may intercept the upward movement of the type bar. After the type bars have been positioned in a selected column in printing position opposite the platen 134 the usual printing hammer 135 is tripped to cause an impression to be made on the record in the usual manner. The type bars move upwardly to present the various type to printing position in synchronism with the passage of the record card by the lower brushes 33.

Referring now to Fig. 4 in which is shown diagrammatically the relative positions of the parts now being considered, during the passage of a single index point position by the brush 33'the three notches 130 corresponding to the three characters which have a perforation in that particular index position will move past the stopping pawl 131 and the corresponding type will move past the printing position of the platen. For instance, an inspection of the card in Fig. 8 will disclose that the digit 5 and the alphabetical characters G and T all have a perforation in the 5 index point position. In Figs. 4 and 6 these three characters are located adjacent to one another so that as the 5 index point position traverses the brush 33 the notches 130 representing 5, G and T will successively pass the toe of the pawl 131. Brush 33 is of suflicient width to maintain contact through the perforations during the passage of the three related notches and the distributing commutator under control of the upper brushes will determine at which point in the passage of a trio of notches the pawl 131 is to be tripped. For instance, reconsidering a perforation in the 5 index point position, the presence of an accompanying perforation in the 12 position to represent the letter T will set the distributing mechanism so that the tripping of the pawl 131 as the 5 index point position is cooperating with brush 33 will be delayed until the notches corresponding to 5 and G have passed. Likewise, if an 11 perforation accompanies the 5 hole, pawl 131 will be tripped immediately after the 5 has passed. And thirdly, if there is no controlling perforation in the 11 or 12 position the pawl 131 will trip earlier to catch the type bar in 5 position. Referring now to the wiring diagram of the device (Fig. 9) the upper brushes are represented at 32 and the lower brushes at 33. The circuits will flow through the device from one side of line to the opposite side 141. A cam contact 142 is provided to permit current to flow from line 140 to the brushes during the passage of the index points 11 and 12 only. The occurrence of a perforation in either of these positions will complete a circuit from line 140, contact 142, common bar 143, perforation in the card, brush 32, wire 144, magnet 55, wire 145, to other side of line 141. This as has already been explained in detail in connection with .Fig. 3 will position the corresponding slider 62 so that either of the contacts 90 or 91 will, close. If no perforation is sensed by the brush in these two index positions, the contact 92 will be closed. In the wiring diagram the uppermost set of contacts 90, 91 and 92 has been positioned to indicate that the character has no controlling perforation 11 or 12. Consequently, contact 92 is closed. In the second set, contact 91 is closed, indicating a 12 perforation. In the third set, contact 90 'is closed to represent a character in the field having a perforation in the 11 position. These contacts, as has been explained, are so positioned during the passage of the card by the upper brushes 32 and remain in this position during the passage of the same card by the lower brushes 33. Current is supplied to the brushes 33 from line 141. through a cam contact 146 and common bar 147.

The distributing commutator 49, shown in development, has its three brushes 52a, 53a, 54a, connected to wires 52b, 53b, 54b, to which are respectively connected the contacts 92, 90, 91, having in mind that during the passage of any index point by the lower brushes the three commutator inserts 52, 53, 54 will successively cooperate with their respective brushes while the brush 33 is making contact through the perforation in the card in that position.

The manner of selection may more readily be explained by means of a specific example: Assume for instance that the column containing a 9 perforation passed through the machine if there were nocontrol perforation contact 92 would have been closed as the card passed the.

upper brushes. Arriving at the lower brushes the circuit through the 9 hole would be completed immediately upon the presentation of insert 54 to its corresponding brush 54a. The completed circuit about to be traced will then intercept the type bar to present a nine to printing position. The circuit flows from line 140, to common ring 51 of the distributor insert 54 cf the 9 position, brush 54a, wire 54b, contact 92, magnet 133, wire 148, corresponding brush 33, bar. 147, contact 146, back to line 141. If the character perforated in the column represents the letter Y, the circuit would have been completed when the insert 53 of the 9 position came to contact with its brush 53a and the circuitwould follow to the wire 53b to the lowest contact 91 and thence through magnet 133 in the same manner to interrupt the type bar in the last of the trio of notches corresponding to the 9 index point position of the card.

According to the card (Fig. 8) it will be observed that two characters A and M are represented by control holes in the 11 and 12 positions only. Considering a perforation in the 11 position only the sensing of the column by the upper brushes 32 will cause closure of contact in the regular manner. During the rotation of the distributor 49 a special insert 530 will contact with the brush 53a immediately after the passage of the last three characters associated with the zero perforation.

The sensing of the M perforation in the 12 position will cause closure of contact 91 and the consequent later completion of the circuit when a special insert 52c contacts with brush 52a. These two inserts 52c and 530 are so located that the time of completion of the circuit will follow immediatly after the sensing of the zero index position by the lower brushes. This is done to maintain a uniform spacing between the various type elements, as will be noted in Figs. 4 and 6. The configuration of the type bar cams 115 is such that as the card is passing the sensing brushes between the 11 and 12 index point positions, the type bar is rising at a lesser rate and the M position reaches the printing line simultaneously with the sensing of the 12 index point positions.

After a card has completely passed the lower brushes, the contacts 90, 91, 92 are restored and immediately set to a new combination of positions in accordance with the reading of the next succeeding card about to pass the lower brushes. This reading, as will be recalled, was taken on the passage of this card by the upper brushes and its imposition upon the contacts 90, 91, 92 delayed until the card approached the lower brushes. In this manner the same set of. contacts 90, 91, 92 may be utilized for each successive card without the necessity of skipping any card reading cycles or the provision of an alternate set of contacts which is usually necessary in other translating devices of this character where the complete sensing of a card requires two cycles, one for determining the zone and the other for selecting the particular position in that zone.

While there has been shown and described and pointed out the fundamental novel features of the invention as applied to a single modification, itwill be understood that various omissions and substitutions and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art without deparing from the spirit of the invention.
